deposited uponfisaid .vva,1l out through the tached to-levei'.11, at15,-and its other end attached to lever" 12 ,"at 16. Lever 12 is shown provided witha projection 12? on one side adapted to engage the lever 11 underthe normal action of spring 14, whereby said spring andprojection 12 serve to cause the levers 11 and 12 to assume the normal posit'ions shown in Figs. 1 and 2, when the lever 11 is not restrained, andto permit the lever 12 to move relatively to lever 11 when the foe latter. is restrained, for the rejection of spurious coins and tokens, as illustrated in Fi' .5.. Y

Fhe top wall ,1 of easing '1 is shown curved on an are described around the center of stud 13, and is cut away forming an opening at 1, to permit the passage and play therein of the fiiiger piece extension 12 of lever 12. Lever 12 carries a shield 17, curved to correspond to wall 1 and overlying the latter so as to slide thereon when lever 12 is rocked, and thereby to close the opening 1. The shield 17 is provided with a coin slot 17 which, when the levers are in the normal positions shown in Fig. 1, is in register with the opening 1 for the admission of a coin, but when the lever 12 is inoved to the right, as in Figs. 2 and 5,

' the slot 17 overlies the wall 1', and prevents the insertion of a coin. spring 18 connected with casing 1 and wlth lever 12 serves to normally draw the latter, and with it the lever 11 and'the ejector 8, to the nor mal positions shown in Fig. 1, withlever' ward the left in Fig. 1 when lever 12 is in the normal position shown in said figure, whereby the coin a that is passed through slot 17 and drops upon ledge 19 will tend to roll from said ledge to the controlling devices forreleasing the lever 11, unless a spurious coin or token be inserted through the coin slot. At a distance to one side of and below the ledge19 is a second ledge 20 upon lever-12, onto which ledge the coin or 'token will fall from ledge 19, unless otherwise prevented, as hereinafter .explained. Beneathdedge 20 is a coin projection 21' extending from a latch 21 that is weighted so as to normally engage the upper end of lever 11 to prevent operation of the latter except when released by a proper coin. Latch 21 is shown pivotally supported upon casing 1 by the pivot 22, and provided with a tooth 21 to coact with either of two teeth 11 on lever 11.

' the position shown in Fig. 1' lever 11 is re tained in normal position, but after opera tion of lever 11 one set of said teeth will retain. lever 11 in an intermediate position if a person should attempt to obtain an extra article 3 by swinging lever 12 back and forth. Lever 12 carries a depending coin guiding finger 23, normally adjacent to projection 21' in such position as to cause the proper coin that passes from ledge 20 to engage said projection. Upon lever 12 is secured a plate 2% (Fig. 3), that lies against ledges 19 and 20 in such position as to pro vide a channel or space 25 between plate 21 and the upper part of lever 12 and finger A 23 for guiding a coin, on edge, in its passage from\ slot 17 to ledge 19, thence to ledge 20, and thence along the finger 23 to projection 21*. Beneath finger 23 is a suit-- able receptacle 26 for the coins.

At 27 is a coin releaser, shown pivotally supported upon casing 1 at 28, and hanging by gravity inopposition to the projection 21", the relation of the parts 27 and 21 being such'that a coin of proper diameter will rest temporarily therebetween on edge, the weight of such coin, however, after dropping from ledge 20 into engagement with projection 21*, serving to tilt latch 21 l Vhen said teeth are into raise its tooth out of engagement with the teeth 11 of lever 11, the upward swing of latch 21 at such time being limited by a stop 29 upon lever 12, whereby the coin is retained between parts 21' and 27. At such time levers 12 and 11 are released, and may be moved together to cause ejector 8 to operate, as in Fig. 2. As lever 12 is thereupon moved, the coin is to be released by moving the releaser 27 from in front of the edge of the coin. For this purpose releaser 527 is provided with a laterally disposed projection 27" (Figs. 8 and 9) adapted to be engaged by an inclined projection 30 carried by finger 23 in such position that,

after lever '12 has been tilted a suitable distance, the projection 30 riding upwardly against projection 27 will cause the latter to be moved away from the edge of the coin (see dotted lines in Fig. 9), thereby releasing the coin. The coin thus releases the latch 21 and falls into the coin receptacle 26. Latch 21 may then rest upon the upper edge 11 of lever 11 (Fig. 2) in position to engage and retain lever 11 when the latter next returns to normal position.

From the foregoing it will be understood that when the parts are in the normal positions and Latch 21 is in engagement with lever 11, the lever 12 may be tilted regardless of theinsertion of a coin; lever 11, however, cannot be tilted or operated until a coin has been inserted in the coin slot and has fallen into place between the parts 21. and 27, and by its weight has caused latch 21 to be lifted from lever 11. At such time when lever 12 is tilted, the tension of spring 14 (causing projection 12 to bear against lever 11) will enable lever 11 to be moved with lever 12 to cause ejector 8 to pull out the lowermost ar ticle 3 from the stack (Fig. 2), and thereupon the coin releaser 27 will be moved to release the coin. As the lever 12 may be released to be drawn back quickly by spring 18, the lever 11 with the ejector 8 may thus be quickly thrust under the stack of articles, since the free end of the ejector 8, when the levers 11, 12 have been moved, (as in Fig. 2) will rest under the adjacent edge portion of the lowermost article 3, as indicated in Fig. 2 with respect to the weight 3*. Such quick motion of lever 11 and finger 9 would tend to forcibly eject article 3 from wall (,6 through opening 7. To prevent the articles from being forcibly ejected through opening 7 I provide means to retard their exit when pushed by finger 9. For this purpose I have shown a movable member 31 beneath shelf 4 adapted to obstruct the passage of the articles 3. Said member may be in the form of a weight pivoted to "casing 1 at 32, and normally held in position to permit an article 3 to slide beneath it, yet to be retarded in its exit by resting thereon. For this purpose I have shown member 31 provided with moved backby saida-rticles as they pass una prdj'ection 3'1 resting upon a: stop 33,-

wherebymember iil is normally in the path of the article's "being ejected and may be der the same, as projected finger 9,. yet Wlll drag on the article's. Thearti'cle a my then rest in position to be withdrawnby the purchaser, as indicated in dotted lines in Fig. 1.

As so far described the machine, is adapted to operate in conjunction with a proper co n. In order to prevent the machine from being operated upon the insertitin of spurious coins or tokens, that are not of the proper thickness, diameter or Weight, or have other characteristicsdiffering from a proper coin, I provide the followin arrangements: The normal space between the opposed surfaces of projection 21 and releaser 27 is such as to support the proper coin therebetween when the latter has caused latch 21 to be tilted against stop 29 and before releaser 27 has been moved to release the coin, but if a token of less diameter'than such coin be inserted it will slide between the parts 21 and 27 into the receptacle 26 with out operating the latch to release lever 11. Again, the space between plate 24 and finger 30 is of such width that a coin of proper thickness will properly rest between projection 21 and releaser 27 but a coin ortoken of lighter weight than a proper coin will be.

unable to operate the latch 21 to release le- 12, at a point adjacent the coin delivery edge of ledge 19 and at such a distance from the opposing edge of ledge 20 as that the token may fall (as indicated in dotted lines in Fig. 1) into the space between parts" 35 and 20 and down upon the inclined edge 36 on lever 12, that is located below magnet 35 in position to direct the token into receptacle 26 asthe token falls between the lever 12 and cover 1. Thus, when such token is inserted in slot 17? and rides along ledge19 it will be attracted. by magnet 35 and caused to descend between said magnet and ledge 20 to prevent it from jumping or passing from ledge 19 to ledge 20, thereby to be deposited without engaging latch 21. In case a token having a hole therein, such as a washer b (Fig. 2) is inserted through slot 17*1 pro vide means to prevent such token from reaching the projection 21 as follows: Upon lever 12, below slot 17 is pivoted a finger 38,

ing' in the path of thejtoken' resting upon led e 19.

38 is provided with a projection 38? extending oppositely thereto, (Fig. 7), adapted" to engage an inclined edge 41 i famed on a suitable block '42 secured on ken, and the continued movement of lever 12 will cause pin 40 to gradually push'the token along ledge 19 to drop between ledges 19 and 20 upon ledge 36, and thence into receptacle 26, since, when the token is caught by finger 38', it is prevented from rolling suddenly from ledge 19 to ledge 20, but is carried past the vertical cente'r pass ing through stud 13 (to the 'ri'ghthand side thereof as illustrated in Fig. 2), and will drop by gravity between ledges 19 and 20 when pushed ofl' ledge 19 by pin 40.

y In order to prevent the continued operation of a coin or token against the latch 21 a when such coin or token is attached to a string or the like, I. may provide the ledge 20f-with an inclined inner edge 20* ('Fi 2) spaced from the lever 12, whereby if such coin or token having a string attached be insertedthrough the coin slot and passes mit one lever to move independently'of the other,- one of said levers having means to eject articles from the casing, means separate from the ejecting means to lock one of said levers from movement andcontrolled by a coin to release the last 'name'd lever for movement with the other lever, and means to admit coins into the casing.
